Phase 2 |
Detailed Description
This is a two-site randomized controlled trial taking place at Beth Israel Deaconess Medical Center in Boston, MA and The Miriam Hospital in Providence, RI. Seventy (n=70) physically inactive ACS survivors will be randomized to either a 6-month group tai chi program (remotely-delivered classes on Zoom) integrated with a wearable self-monitoring/feedback device plus enhanced usual care (EUC), or to EUC alone. EUC will include usual care provided by participants' providers integrated with printed CHD risk factor education materials. Assessments will be conducted in-person at baseline, 6 months (end of treatment), and 9 months. Our primary outcomes will be focused on study feasibility and acceptability. Secondary outcomes include the following patient-centered outcomes: objectively measured (via accelerometry) moderate-vigorous physical activity, light physical activity, sedentary time, cognitive-behavioral constructs (exercise self-efficacy, intrinsic motivation, depression, stress, HRQL), and cardiometabolic measures (exercise capacity, body weight, lipid profile, blood pressure, fasting plasma glucose).
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Tai chi + wearable 48 virtual tai chi classes on Zoom over 6 months plus assigned home practice of tai chi 3x a week plus daily use of a Fitbit fitness tracker will be required for this group. |
Behavioral: Tai chi + wearable
The tai chi intervention will be delivered remotely via Zoom Enterprise. Participants will access classes on a phone, tablet, laptop, or desktop computer. Participants will attend 3 classes/week (each lasting 60 min) during weeks 1-12, 2 classes/week during weeks 13-16, and then 1 class every other week during weeks 17-24. Classes include tai chi warm-up exercises, breathing exercises, review and practice of tai chi forms, and cool-down exercises. Participants will be asked to practice tai chi at home 3x per week during the 6 month intervention period using an instructional video provided to them. The Fitbit fitness tracker will be given to each participant along with instructions on how to use the tracker and the Fitbit app on their personal device.

| No Intervention: Enhanced usual care Printed educational materials based on existing resources (e.g., AHA; Centers for Disease Control and Prevention) will be shared with subjects in this group. |
Outcome Measures
Primary Outcome Measures
- Recruitment rate [Through study completion (an average of 3 years)]
Recruitment rate will be evaluated with respect to rate of enrollment, defined as randomization into the trial.
- Retention rate [Through study completion (an average of 3 years)]
Retention rate will be quantified by the proportion of subjects who remain in the study to complete our 9-month visit.
- Intervention enjoyment [6 months]
Intervention enjoyment will be assessed via qualitative interviews
- Intervention adherence [Through study completion (an average of 3 years)]
Intervention adherence will be measured by collection of class attendance and home practice data.
Secondary Outcome Measures
- Physical activity [Baseline, 6 and 9 months]
Physical activity will be measured using accelerometers (Actigraph model wGT3X-BT, LLC, Fort Walton Beach, FL).
- Systolic and diastolic blood pressure [Baseline, 6 and 9 months]
Blood pressure will be measured using a Dinamap XL automated BP monitor according to current recommendations.
- Body weight [Baseline, 6 and 9 months]
Body weight will be measured using an electronic scale.
- Height [Baseline]
Height will be measured using a tape measure.
- Fasting glucose [Baseline, 6 and 9 months]
Fasting glucose will be measured after a 12-hour fast according to standardized procedures. All blood samples will be sent to and analyzed at the Lifespan Laboratory located at the Rhode Island Hospital/The Miriam Hospital.
- Lipid panel [Baseline, 6 and 9 months]
Lipid panel will be measured after a 12-hour fast according to standardized procedures. All blood samples will be sent to and analyzed at the Lifespan Laboratory located at the Rhode Island Hospital/The Miriam Hospital.
- hs-CRP [Baseline, 6 and 9 months]
hs-CRP will be measured after a 12-hour fast according to standardized procedures. All blood samples will be sent to and analyzed at the Lifespan Laboratory located at the Rhode Island Hospital/The Miriam Hospital.
- Quality of life assessed by SF-36 [Baseline, 6 and 9 months]
Quality of life will be measured using a short version (8 items) of the Health Survey Short Form (SF-36). Scores range from 0-100, with a higher score indicating a higher quality of life.
- Intrinsic motivation [Baseline, 6 and 9 months]
Intrinsic Motivation Inventory is a 22-item scale validated with four sub-scales: interest/enjoyment, perceived competence, perceived choice, and pressure/tension. A higher score is better, with a scoring range of 22-154.
- Anxiety, Depression [Baseline, 6 and 9 months]
Anxiety, Depression will be assessed using the Hospital Anxiety and Depression Scale, a self-administered questionnaire with two sub-scales (0-21) measuring anxiety and depression, with higher scores indicating greater psychological morbidity.
- Stress [Baseline, 6 and 9 months]
Stress will be measured using the Perceived Stress Scale (PSS) - a 10 items survey with scores ranging from 0 to 40, and higher scores indicating greater stress burden.
- Mindful awareness [Baseline, 6 and 9 months]
Mindful awareness will be assessed using the Five Facets of Mindfulness questionnaire (short form) a 15-item questionnaire that measures the five identified components of mindfulness meditation: observing, acting with awareness, non-judging of inner experience, and non-reactivity to inner experience. Scores ranges from 39-19, with a higher score being better.
- Exercise self-efficacy [Baseline, 6 and 9 months]
Exercise self-efficacy will be measured using the Self-Efficacy for Exercise Scale. This is a 9-item validated scale from McAuley's original barriers scale. Scores range form 9-28, with a higher score meaning more self-efficacy.
- Exercise capacity [Baseline, 6 and 9 months]
Exercise capacity will be assessed via the 6 min walk test (6MWT), a simple, safe and reliable first-line assessment of functional status that correlates with peak oxygen uptake.
Other Outcome Measures
- Socio-demographics [Baseline]
Age, sex, race/ethnicity, education, income, insurance status will be collected from the EMR using standard abstraction forms.
- Medical history [Baseline]
Coronary risk factors; coronary revascularization procedures; ejection fraction; New York Heart Association class; CHD severity (one-, two- or three-vessel from coronary angiogram); co-morbidities; CR information (history of participation, reasons for decline); comorbidities (Charlson index); medications] will be abstracted from medical records using standard abstraction forms that have been validated in previous studies.
- Social support [Baseline]
Social support will be measured with the Multidimensional Scale of Perceived Social Support is a 12-item, unidimensional tool to measure how one perceives their social support system, including the individual's sources of social support (i.e., family, friends, and significant others). Scores range from 12-84, with a higher score meaning more perceived social support.
- Neighborhood barriers to physical activity [Baseline]
PANES (Physical Activity Neighborhood Environment Survey) also known as the International Physical Activity Prevalence Study Self-Administered Environmental Module is a 17-item Scale that can be used to assess the environmental factors for walking and bicycling in various neighborhoods. Scores range from 17-68, with higher scores indicating a neighborhood environment that is more conducive to physical activity.
